They are suitable for voltage withstand tests of household appliances such as televisions, fans, tape recorders, refrigerators, washing machines, microwave ovens, hair dryers, and for electronic whole machines such as instruments and meters. They provide testing means for the implementation of national safety standards, thereby highlighting their importance. They have become an indispensable instrument and equipment for scientific research institutions, metrological testing departments, and the electronics industry in detecting electronic instruments and household appliances, etc. They comply with the standards of...GB4706.1》Standard.

This series of instruments boasts an aesthetically pleasing design and easy operation, with output voltage clearly displayed on a digital panel for precise, intuitive, and accurate readings. The entire unit is technologically advanced with a well-organized layout, featuring high accuracy, excellent reliability, and easy maintenance.

Working Principle

（1Relay: This electrical control220VIs the power connected to the regulator, thereby controlling the engagement or disconnection of the high-voltage output?

（2Voltage Regulator: Primarily composed of a voltage transformer, the change in voltage is achieved through the regulation of this transformer.

（3High-voltage Transformer: By adjusting the voltage regulator knob, the input voltage of the high-voltage transformer is increased, from which high voltage is obtained. Direct AC voltage output

（4Current Detector: This part of the circuit converts the current flowing through the measured item into voltage, compares it with a reference voltage, and then outputs a detection signal to the controller.

（5The controller: controls the relay's connection and the alarm circuit's alarm based on signals from the current sensor, start/reset button, and timer.

（6The timer: After pressing the start button, the high voltage is connected, and the timer begins to countdown. Once the timer reaches zero, the control circuit disconnects the high voltage, thereby achieving the purpose of timed testing.

（7Alarm: During the testing process,When the leakage current exceeds the set leakage current preset,The driver module powers the buzzer and ultra-leakage lamp to produce an audio-visual alarm.,Simultaneously, it automatically cuts off high voltage.
